Description

Control method for used temperature of bidet

The present invention relates to a bidet, and more particularly, to automatically control the washing water heating temperature and/or toilet seat temperature in response to seasonal temperature changes of raw water supplied through a water faucet when a smart care mode is selected by a user. It relates to a method of controlling the temperature of use of a bidet.

In general, a bidet is located on the toilet seat of a toilet in a lodging establishment or a general home, and is widely used as a toilet seat facility. The bidet replaces toilet paper because it removes filth by spraying washing water to and around the person's anus and/or local area through nozzles after a person's toilet, which is a body having a built-in heating part toilet seat coupled to the toilet , a manipulation unit, and a nozzle unit for spraying washing water to and around the user's anus and/or local area, and a heating unit for heating the washing water sprayed through the nozzle unit (eg, a heater and/or instantaneous water heater), etc. will do

At this time, in the conventional method of controlling the heating temperature of the washing water in the bidet, if the current temperature of the washing water in the storage tank sensed by the temperature sensor is lower than the set target temperature, 100% of power is applied to the heating unit, and the power is supplied and then stored. When the current temperature of the washing water in the tank is higher than the set target temperature, the power applied to the heating unit is turned off.

In addition, the method of controlling the heating temperature of the toilet seat in the conventional bidet is to turn on or off the heating unit built into the toilet seat according to the target temperature in a state in which the target temperature is set.

However, in the temperature control method of heating the washing water or the toilet seat by setting the target temperature as described above, when the toilet seat is heated by applying 100% power to the heating unit or the washing water in the storage tank is heated, the toilet seat or the washing water temperature is increased. There was a problem of overheating and not being able to accurately control the heating temperature of the toilet seat or the heating temperature of the washing water sprayed in real time.

In addition, in the temperature control method of heating the toilet seat or washing water by setting the target temperature as described above, the user sets the target temperature through the operation unit, so the toilet seat is heated according to the season (eg, spring, summer, autumn, winter). Alternatively, there is a problem in that when raw water of different temperatures supplied through a water hydrant is heated by a heating unit, power consumption is inevitably different, and thus unnecessary power is wasted.

In addition, in the case of the conventional bidet, once the target temperature is set through the operation unit, it is difficult to reset the target temperature through the operation unit in the case of a child of a low age group or the elderly with a high age group. Alternatively, washing water had to be used, and in this case, certain users (eg, children, the elderly) complained of discomfort due to a toilet seat heated to an undesirable temperature or washing water.

The method for controlling the use temperature of the bidet according to the embodiment of the present invention as shown in FIG. 3 is achieved by the configuration of the bidet of FIGS. 1 and 2, and the bidet is coupled to the toilet with a second heating unit (60) A nozzle unit 50 capable of linear movement and/or rotation in the left and right directions to spray the washing water on and around the user's anus and/or local area to a body (not shown) having a built-in toilet seat, the nozzle unit 50 A first heating unit 40 for heating the washing water sprayed through the bidet control unit 30 for controlling the nozzle unit 50, the first heating unit 40, and the second heating unit 60 , which may include a manipulation unit 10 that is fixedly or rotatably coupled to the body.

At this time, as shown in the attached figure 2, the operation unit 10 has stop/water flushing, washing/move, bidet/move, drying, water pressure drying temperature, nozzle position, nozzle washing, power saving/power, toilet seat temperature, hot and cold massage. Function buttons for selecting , children, deodorization, etc. are formed, as well as function buttons of mode selection for selecting the smart care mode (M1) and the hot water control mode (M2) can be formed.

Here, the functional units (eg, drying device, washing device, deodorizing device, etc.) corresponding to each function button formed on the operation unit 10 may be normally formed in the bidet body, and detailed descriptions thereof are given below. to be omitted.

On the other hand, although not shown in the drawings, the temperature sensor 20 is formed at the body receiving end of the bidet to which the water hydrant is connected, or the first heating unit 40 is a hot water tank provided inside the body of the bidet. It may be formed at the receiving end of the hot water tank when it is a hot water heater formed in will be.

Therefore, in the method for controlling the use temperature of the bidet according to the embodiment of the present invention made in the bidet as described above, the use temperature is to control the toilet seat temperature and/or the washing water temperature, and the smart K-mode (M1) and the hot water control From the selection of the mode (M2), the raw water supplied from the water faucet is converted to washing water heated to a certain temperature, and then it is sprayed through the nozzle unit 50 and/or the temperature of the toilet seat can be controlled, This includes steps (a), (b), (c), and (d).

In step (a), it is determined whether the bidet user has selected the smart care mode M1 provided in the manipulation unit 10 .

That is, among bidet users, the first user group (eg, adolescents, adults, etc.) who can freely set various functions through the operation unit 10 while familiarizing themselves with how to use the bidet, and the method of using the bidet, or the operation unit ( There may be a second user group (eg, children, the elderly, etc.) that cannot properly set various functions through 10). In step (a), the smart care mode (M1) ) to determine whether a selection has been made.

In the following step (b), when it is determined that the user has selected the smart care mode (M1) as a result of the determination in step (a), the temperature sensor 20 detects the temperature of the raw water supplied to the bidet through the water faucet. After sensing, the output is made to the bidet control unit 30 .

The following step (c) allows the bidet control unit 30 to determine any one of the four seasons according to the temperature of the raw water detected by the temperature sensor 20 from the step (b). will be.

That is, the bidet control unit 30, as shown in the attached FIG. 4, the raw water acquisition temperature sensed by the temperature sensor 20 from the step (b) in the first temperature range (eg, 10 ℃ ~ 19 ℃) ) is to be determined as spring or autumn among the four seasons, and a second temperature range (eg; When detected within 20 ° C. to 34 ° C.), it is determined as summer among the four seasons, and the temperature of the raw water detected by the temperature sensor 20 from step (b) is a third temperature range lower than the first temperature range. If it is detected within (eg 3℃~9℃), it is judged as winter among the four seasons.

Here, since the raw water supplied through the hydrant is connected to the bidet through a hose or the like to supply the raw water to the bidet after receiving the raw water from a pipeline buried underground, the raw water flowing to the hydrant through the pipeline is seasonal They can only have different temperatures.

In the next step (d), according to the season determined from step (c), the bidet control unit 30 controls the heating amount of the first heating unit 40 while heating the raw water supplied through the water faucet, The temperature of the water outlet of the washing water to be sprayed through the nozzle unit 50 is controlled by interlocking with the season.

That is, when the bidet control unit 30 determines that the season is spring or autumn from step (c), as shown in the attached FIG. 4 , the heating amount of the first heating unit 40 composed of a hot water heater or an instantaneous water heater It is to control to supply driving power having a first current amount matching the intermediate value to the first heating unit 40 so as to be controlled to the intermediate value, and when the season is determined as summer from the step (c), the first Supply driving power having a second current amount lower than the first current amount and matching the lower value to the first heating part 40 so that the heating amount of the heating unit 40 is controlled to a lower value lower than the intermediate value control, and when it is determined that the season is winter from step (c), the first heating unit 40 is sent to the first heating unit 40 so that the heating amount of the first heating unit 40 is controlled to an upper value higher than the intermediate value. The control is to supply the driving power having a third amount of current higher than the first amount and matching the upper value.

Then, the first heating unit 40 to which the driving power supply having the first amount of current, the second amount of current, or the third amount of current is supplied is not a predetermined uniform target temperature, but the raw water to have a temperature linked to the season. As the nozzle unit 50 is heated, the washing water heated to the water outlet temperature linked to the season is sprayed. The second user layer, such as children or the elderly, who cannot properly set the operation unit 10, can receive local and/or anus cleaning without discomfort by spraying the washing water that maintains an appropriate temperature even if the operation unit 10 is not complicatedly operated.

That is, when it is determined by the bidet control unit 30 to be spring or autumn, the temperature of the water outlet of the washing water sprayed through the nozzle unit 50 is maintained in the range of 31°C to 39°C as shown in the attached FIG. 4 . It is heated, and when it is determined that it is summer, the water outlet temperature of the washing water sprayed through the nozzle unit 50 is heated to be maintained in the range of 28°C to 30°C, and when it is determined as winter, washing is sprayed through the nozzle unit 50 The water outlet temperature is heated to maintain 40° C. or higher so that the spray can be made.

In addition, as an embodiment of the present invention, in step (d), when the bidet user selects the hot water control mode M2 provided in the operation unit 10 to set the target temperature, the bidet control unit 30 The driving power having a fourth amount of current equal to or higher than the third amount of current may be supplied to the first heating unit 40 until the set target temperature is reached.

That is, if a target temperature of the temperature of the washing water sprayed through the nozzle unit 50 is set through the hot water control mode M2, when the second user layer uses a bidet, the nozzle unit 50 The washing water reaching the target temperature can be sprayed on the user's anus and/or local area, which corresponds to a known technique practiced in the prior art.

On the other hand, as an embodiment of the present invention, in the step (d), the bidet control unit 30 heats the second heating unit 60 which is a toilet seat heater built into the toilet seat according to the season determined from the step (c). By controlling the amount, it is also possible to control the temperature of the seated toilet seat by interlocking it with the season.

That is, the bidet control unit 30 is configured to control the heating amount of the second heating unit 60, which is a toilet seat heater, to an intermediate value when determining that the season is spring or autumn from step (c). 50) is controlled to supply driving power having a first current amount matching the intermediate value, and when the season is determined as summer from step (c), the heating amount of the second heating unit 60 is the intermediate value It is to control to supply driving power having a second current amount matching the lower value while being lower than the first current amount to the second heating unit 60 so as to be controlled to a lower lower value, and seasonal from step (c). When it is determined as winter, the second heating unit 60 is higher than the first current amount and matching the upper value so that the heating amount of the second heating unit 60 is controlled to an upper value higher than the intermediate value. 3 It is to control to supply the driving power having the amount of current.

Then, the second heating unit 60 to which the driving power supply having the first amount of current, the second amount of current, or the third amount of current is supplied has a temperature that is linked to the season rather than a predetermined uniform target temperature. As a user group using a bidet, the second user group, such as children or the elderly, who do not properly understand how to use a bidet or cannot properly set various functions through the operation unit 10, complicates the operation unit 10. Even if you don't operate it, you can be provided with the temperature of the toilet seat that maintains an appropriate temperature.

In the above, the technical idea of the bidet use temperature control method of the present invention has been described along with the accompanying drawings, but this is an exemplary description of the best embodiment of the present invention and does not limit the present invention.

Accordingly, the present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the present invention as claimed in the claims. It is, of course, possible that such modifications are intended to be within the scope of the appended claims.
